The unsubstituted ortho-amidino benzoic acid: crystal structure, characterization and pK a determination

The simplest o-amidino benzoic acid—2-(amino(imino)methyl)benzoic acid—has been isolated in 23 % yield as a side product of the reaction of phthalonitrile and ammonia along with desired 1-imino-1H-isoindol-3-amine. This amidino acid was fully characterized by nuclear magnetic resonance, IR spectroscopy, mass spectrometry; pKa values were also determined. X-ray diffraction study and quantum chemical calculations revealed that in the solid state it exists as a zwitterion that is stabilized by intermolecular hydrogen bonds.

A One‐Pot Synthesis of 3‐Amino‐1H‐isoindol‐1‐one thiazol‐2‐ylhydrazones

A reaction of phthalonitrile with thiosemicarbazide and α‐haloketones proceeded in one‐pot, giving rise to 3‐amino‐1H‐isoindol‐1‐one thiazol‐2‐ylhydrazones in high yields.

Synthesis, spectra and conductivity of 1-D polymers of nickel(I)-and copper(II )-porphyrazine with sulfur bridges

The title polymers PNIPzS4 and PCuPzS4 were synthesized by reaction of phthalonitrile and 2,3,5,6-tetracyano-1,4-dithiin with corresponding metal salt. Their structures and properties were characterized by associating the experimental results with MO and Cl calculations of the dimer molecule as model polymer in the ZINDO method. It has been found that the PNiPzS4 (or PCuPzS4) shows the semiconductivity at T < 253 K (or 260 K) and T > 278 K (or 286 K) and the conductivity increase with a hoist of temperature at 253 K (or 260 K) < T < 278 K (or 286 K). The conductivity σ of the PNiPzS4 and PCuPzS4 under pressure 13.73 MPa is 1.56×10−4 and 9.33×10−5 S/cm, respectively.

Soluble (Phthalocyaninato)ruthenium(II) Phosphane Complexes

AbstractHitherto unknown ruthenium phthalocyanine complexes with phosphane ligands – PcRu(PEt2Ph)2 (1) and PcRu(PPh3)2 (2) – soluble in common organic solvents were prepared. Two methods were used for their synthesis: 1) Reaction of phthalonitrile with [Ru2Cl3(PEt2Ph)6]Cl in n‐pentanol in the presence of 1,8‐diazabicyclo[5.4.0]undec‐7‐ene (DBU) and 2) reaction of PcRu with the corresponding phosphanes. The products 1 and 2 were characterized by their IR, UV/Vis, FD‐MS, and 1H‐NMR data.

Condensation of phthalonitrile with weakly basic diamines

It has been found that, in contrast to the condensation of phthalonitrile with diamines with pKa > 2.7, the principal products from which are macroheterocycles, reaction of phthalonitrile with diamines with pKa ≤ 2.7 gives linear condensation products of the reactants.

Reaction of phthalonitrile with p-phenylenediamine in phenol

1. A kinetic study has been made of the condensation of phthalonitrile and p-phenylenediamine in phenol medium, and a mathematical description of the reaction kinetics has been given. 2. A scheme is proposed for the principal path of formation of the macroheterocycle.

ChemInform Abstract: FORMATION OF ISOINDOLE DERIVATIVES DURING REACTION OF PHTHALONITRILE WITH SODIUM METHOXIDE

Formation of isoindole derivatives by reaction of phthalonitrile with sodium methoxide

It is shown by means of IR spectra that the reaction of phthalonitrile with sodium methoxide in benzene in the presence of traces of water or methanol proceeds via a series-parallel mechanism in two steps to give cyclic products. The proposed structure of the intermediate is an oligomeric isbindolenine chain with terminal NNa and OCH3 groups. The final product is the sodium salt of monomethoxyiminoisoindolenine. The analogous reaction in methanol proceeds at a higher rate that makes it impossible to isolate or detect the intermediate; the final product is 1,1-dimethoxy-3-iminoisoindoline.

THE PARTICIPATION OF LIGHT IN THE FORMATION OF PHTHALOCYANINE

Abstract It was found that roomlight accelerates the formation of phthalocyanine in the reaction of phthalonitrile with sodium alkoxide at elevated temperatures. Moreover, UV irradiation gave phthalocyanine even at room temperature where no formation of phthalocyanine was observed without light.

Phathalocyaninato(2--)chromium(III)phosphinates

Abstract : Chromium phthalocyanine (CrPc) was obtained from the reaction of phthalonitrile with Cr(CO)6. CrPc, which converts to CrPcOH upon exposure to air, proved to be a very useful intermediate for the preparation of Chromium (III) phthalocyanine phosphinates. Attempts to find evidence of polymeric forms V by chemical means were unsuccessful of the phosphinates.
